Trump's spokespeople have said he recognizes Russia meddled in the 2016 election, but Trump doesn't appear to be sold on it.

In June, Trump tweeted that the hacking was a hoax, but later that day, White House spokeswoman Sarah Huckabee Sanders said Trump "thinks that it probably was Russia."

Some more recent tweets seem to imply that he believes Russia interfered, but they mostly focus on former President Obama's response to the hacks.

While in Poland recently, Trump said the interference "could" have been Russia, but said other countries might have done it and that "nobody really knows for sure."

He also cast doubt on how much of a consensus there is about it among U.S. intelligence agencies. All four agencies that investigated election meddling said they had "high confidence" that Russia interfered on Putin's orders.
